Résumé
This descriptive-comparative work was carried out with 13 students in the areas of Biology and Chemistry of the Pedagogical Institute of Caracas in a course of Biochemistry, who formed two lab groups. Its purpose was to compare the level of integrative construction of scientific meanings achieved in the concept maps developed in an integrated manner to the V diagram around a problem situation raised on enzymes, considering previous knowledge about this disciplinary content. Student's t statistic was used to compare the level of pre-existing knowledge. A General Index of Integrative Construction of meanings (IGCI) proposed by the authors, was incorporated in a novel way to assess concept maps. The results revealed the discriminatory power of IGCI, being able to differentiate the groups in a more consistent way and in accordance with their levels of prior knowledge.
